Product Description

Gasoline direct injection requires high pressure testing to truly diagnose operation faults. The Revolutionary GDU.4r test bench allows to easily and extensively test and service 4 high pressure Direct injectors up to that high pressure.

BK [electronic]: Dynamic Injection Mass Metering (IVM)

Accurate, repeatable and fast electronic measurement of discharged volumes. Including a metering device that has no moving parts, does not require filtering and temperature calibration. Yet includes Shot-to-Shot and Multiple- Injection-Metering Capability.

Features: Dynamically measuring in mg/stroke (equivalent to mm3/stroke) repeatability : 0.05%, accuracy 0.2%
